Please helpppp (::: this is hard
Yuri [45]

Answer:

sin θ = (√21) / 5

tan θ = (√21) / 2

Step-by-step explanation:

Remember the formulas for the <u>trigonometry ratios</u> with SohCahToa:

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

If cos θ = 2/5, then:

adjacent = 2

hypotenuse = 5

Remember all right triangles follow the <u>Pythagorean Theorem</u>. So if you are missing one side, you can solve.

Let's find the opposite side.

a² + b² = c²

2² + b² = 5²

4 + b² = 25

b² = 21

b = √21

opposite = √21

Now we know all three sides. <u>Use the trigonometry ratios</u> to find sine and tangent.

sin θ = opposite / hypotenuse

sin θ = (√21) / 5

tan θ = opposite / adjacent

tan θ = (√21) / 2

In the rectangle below, the two quarter circles are congruent. Find the area of the shaded of the shaded region.
Delicious77 [7]
Rectangle:
length = 12
width = 6
area of rectangle = length times width = 12 x 6 = 72

area of circle = pi r^2 = 3.14 (6)^2 = 113.1
1/2 circle = 113.1 / 2 = 56.55

<span>the area of the shaded of the shaded region = 72 - 56.55 = 15.45
</span>
